为什么 Bootstrap 轮播标题在开发中可见,但在生产中不可见?

Why Bootstrap carousel caption visible in development but not production?

我在投资组合网站上工作,我在 Bootstrap 轮播中显示屏幕截图。

在 React Development Server Captions 中正确渲染和操作:

npm run start

Development Server Browser

生产版本,阳离子在 HTML 中,但没有明显呈现:

npm run build
serve -s build

Production Server Brower

<Carousel key= {'in-depth'+projectIndex}  activeIndex={pageIndex} onSelect={(i,e)=>{setPageIndex(i); console.log('select-called'); forceUpdate();}} className='col-lg-8 col-md-10' style={{margin: '1.0rem auto',}}>
            {projects[projectIndex].pages.map((page,i) => 
                <Carousel.Item key={projects[projectIndex].pages[i].target+i+projects[projectIndex].title} interval={5000} style={{maxHeight: '75vh', overflowY: page.type == 'vertical-scroll' ? 'scroll' : 'hidden'}} class={i==0 ? 'active' : ''}>
                {page.type == 'video' ?
                <Player playing src={conceptVersion}  height='420' width='720' controls={true} style={{margin: '0 auto', textAlign: 'center'}} className='project-image'/>
                : <img  className="d-block w-100 project-image" src={projects[projectIndex].pages[i].image} alt={projects[projectIndex].pages[i].target} />}
                    <h3 className='carousel-title' >{projects[projectIndex].title}</h3>
                    {page.type == 'vertical-scroll' ? <div></div>
                    : <div id='describe-box' className='carousel-description-box' style={{}}>
                        <p className='carousel-description' >{projects[projectIndex].pages[i].description}</p>
                    </div>}
                </Carousel.Item>)}
        </Carousel>

知道为什么会这样吗?我该如何解决这个问题?

opacity: 1%; 引起 --> 0% 完全透明。在 Projects.css 中:.carousel-description 块
